I think marriage should be like dog licences. I think you should have to renew marriage licences every five years, unless you have children. And I think before you have children you should have to go and pass various tests and get a licence to have a child. Because it’s the most transformative and difficult thing of your life. Far more important [than work]. People don’t understand this, and some people who are highly motivated by work, but when I worked I was always motivated, funnily enough, by the fear of being bad. Because it is so humiliating to make a joke and have no one laugh.
